Do you offer instructions or exploded views, FAQs or other information that belong to a certain product?
Then you can upload this data, assign it to an article and when a customer buys the article,
he automatically receives the file together with the order confirmation mail.
This is not to be confused with digital downloads, for which the customer must first have paid before they are activated.
This module here is about the customer receiving a file immediately together with the purchase confirmation.
